Application led May l, 1900. Serial No. 15,154. (No model.`

To @ZZ whom it may concern.:

Be it known that I, CYRUS M. CARNAHAN, a citizen of the United States, residing at Allegheny, in the county of Allegheny and State of Pennsylvania, have invented certain new and useful Improvements in Dumping-Gars, of which the following is a specification, reference being had to the accompanying drawings, forming part of this specification, in which- Figure 1 is a view in side elevation, partly broken away, of my improved car. Fig. 2 is a partial plan view. Fig. 3 is a central longitudinal sectional view showing the hoppers tipped, the one at the left being in elevation and the one at the right in section. Fig. t is a cross-section on the line IV I V of Fig. l. Fig. 5 is a similar section on the line V V of Fig. l. Fig. 6 is a similar view on the line VI VI of Fig. l. Figs. 7, S, and 9 are detail perspective views of portions of the interlocking mechanism of the car. Fig. 10 is a perspective detail View illustrating a modified construction provided with lateral dischargingchutes. Fig. l1 is a sectional partial plan view of the skeleton framework. Fig. 12 is a detail perspective view of one of the cornerjoints.

My invention relates to the construction of railroad dumping cars or Vehicles for transportation of any loose material or substance; and it consists in the features of construction as shown in the drawings and as hereinafter described.

The invention has in view the cheapening and simplifying in construction of this class of cars and the ease of operation and unloading the entire contents by gravity, as well as rendering the car tight and serviceable when erected in the carrying position.

The outer framework or skeleton of the car is composed of structural metal supported upon the usual trucks, while the dumpingsections comprise the holding or carrying portion of the car and are pivotally mounted in the framework.

Referring now to the drawings, the side and end sills are composed of box-truss members 2, provided with flanges, to which are secured by riveting the upper and lower edges of the outer plates 3. These side and end sills are joined at the corners and form a rectangular foundation for the framework, being supported on the truck bythe bodybolsters,made .of upper and lower channels 4l 4, connected together at the ends and to the lower side of box-truss members, while the lower channel 4: is trussed down, as shown, and at the middle an intervening separating-box 5 is inserted, made of interfitting channels or angleplates. It will be understood that these bodyholsters will be of the requisite strengthand depth and provided with necessary bearings and king-bolts for the trucks. At the top the same frame construction is provided, run ning along the sides and ends, and between these lower and upper frames are intervening strut members 6 of T or angle shape, riveted to the inner fianges of the box-truss side and end sills, preferably with the flat faces outwardly. The framing is further braced and supported by diagonally-disposed truss inembers 7, of angle or other shape, riveted to the side sills and to the intervening strut members, as shown. Across the top the middle portion of the framework may be braced in both directions by means of a cross-brace 7, hinged at one or both ends, so that it may be swung around for clearance or employed, as in Fig. 4, to brace the sides. It will be seen that asthus constructed the framework of the cars is entirely open underneath with the exception of the body-holsters.

Between the side members of the framework are mounted the tilting dump-sections A A, which consist of interior freight receiving and containing hoppers, entirely filling -the space between the sides of the framework,

the side and end walls of the hoppers when in carrying position coinciding with the inner outline of the framework.. The inner ends of the hoppers are open, a space intervening between the inner edges of the side plates sufficient To provide clearance when the hoppers are tilted forwardly, which space is covered by side plates 8, incorporated with the framework and lapping over the ends of the hoppers on the outside, so as to prevent leakage of contents.

The hopper-foundations consist of side and end channels 9, connected by cross-sills 10 of special rolled shape, as shown, or of any other suitable cross-section, upon which sills rest longitudinal sills 1l, of the saine or suitable IOO construction,incorporated with the cross-sills and with the end channels. Upon these longitudinal sills is laid the door 12, of plate metal, upon which flooris built the sides and ends 13 14, of plate, which sides and ends are reinforced and strengthened by outside horizontal box-braces l5 of a cross-section similar to the floor-sills. These box-braces extend around the ends and along the sides to within a short distance of the inner ends, where they terminate, in order to leave the side plates unobstructed to interit between the plates 8 in the action of dumping. The hoppers are pivotally mounted on bolts 16, passing through the side sills 2 and hopper side channels 9 from side to side, suitable reinforcing bearing-blocks 17 18 being mounted adjacent to the meeting faces to give good surface-bearing. The pivotal bolts are placed outwardly slightly beyond the center of gravity of the hopper, so as to facilitate tipping when loaded.

The hoppers when level rest upon the bodybolster and are held up at their inner ends by' means of cross-bars 19, which may be Ts or angles, the ends of, which project beyond the sides of the car and are beveled on the upper outer corners. Links 20 are pivotally mounted in slots cut through the web of supplemental strut members 2l and held in p0- sition by outer inclosing slotted pieces 22. The cross-bars 19 extend across the under side of the inner ends of the hoppers, being trussed, as shown at 23, while to each end of the bars are attached lifting and lowering chains 24, wound around shafts 25, provided with turning wheels 2b at each end, having suitable ratchet-wheel and pawl locking devices. When it is desired to dump the hoppers, the links are thrown up, pins 27 first having been withdrawn,and the ends are lowered by means of chains. The hoppers are then raised, and as the beveled ends of the cross-bars ride up under the links 20 they will fall out over the ends and automatically drop into engagement, thus securely holding the hopper against movement when the pins 27 may be replaced. Extending across from side to side at the middle of the car is a supplemental floor 28, which when the hoppers are raised forms a continuation of their floors and which is maintained in permanent position by any suitable support, as one or more cross girders or sills 29.

In Fig. 10 I have shown an arrangement for discharging the contents of the carat the sides by means of supplemental inclined chutes 30, located immediately below the floor 28 and supported therefrom by a central pier 31. Each end of this pier is tapered, so as to divide the contents of the hoppers and deliver them into the chutes. These lateral chutes may be made permanent or removable, as desired, and do not require further description.

The skeleton construction of the carframework is very light and its strength is ensign comprised in my invention will be readily appreciated by those familiar with this class of rolling-stock, as the contents of the car may be safely carried, utilizing the full capacity of the car, and they may be discharged either centrally or to one or both sides, according to the construction employed.

Various changes and modifications may be made by the skilled mechanic without departing from my invention, since I do not desire to be limited to the exact form shown and described, but to include all such changes within the scope of the invention as expressed in the following claims.
